    My box plans for 3 type-Rs. Will this work?

    Box Plans
    This is my first box so i dont know if this is right or not. When i put in my woofer info it suggested tuning to 24hz, which seemed very very low. I have been told that 35-38 is better suited for my sibs so i put that in. I will be running 3 4omh 10" Type-Rs. Is this box plan valid?
    Here is what the program suggested based on my sub specs.
    Box 1
    I choose the diamentions based on the alpine suggestions with width multiplied by 3. Is this the correct way to go about this?

    so far it looks good. to make sure, take the net volume per woofer, as recommended by alpine, and X3 that number. you have 5.44...thats 1.81cu' each, is that what you want? if so, then

    also i would tune it to about 30-32hz....

    No alpine recommends 1.3 cubes per sub.
    Which would be more like this.
    3.9 Cubes
    3.9 cubes at 32hz
    which of these all is ideal?

    Every box I have ever built using manufacturer specs has been too small. You need to get winISD or BB6 Pro and model the box using the T/S params.

    In fact I had 2 15" ID IDW's once. Rec box size was 1.5 cubes which was a total joke for those subs. I ended up doing 8cubes for both

    Drop your tuning to 30-32hz and remodel it using the T/S params

    That calc thing you had has some inputs for the T/S params.. the Qts, Vas, Fs thing is for that. Set the drop down to SQL though, Maximally flat will have a huge box and the small box will have wacky tuning
